Manufacturing method for camera window having distinctive pattern and camera window having the distinctive pattern

A method of manufacturing a camera window for use in protecting a camera module having an objective lens from external impact, said camera window having a distinctive pattern recognizable by direct external recognition, in which the camera window is provided with a transmission portion at a center thereof, and a pattern is provided around the transmission portion, and wherein the camera window has a front surface and a back surface which are opposite surfaces, the manufacturing method comprising:

• forming a cell-based patterning mask layer on a front surface or on the front surface and a back surface of a glass sheet;
• forming a cell-based pattern layer on the glass sheet by patterning the patterning mask layer;
• forming a cell-based distinctive pattern on the front surface of the glass sheet by etching the front surface of the glass sheet using the pattern layer as a mask;
• removing the patterning mask layer, and forming a shaping mask layer on the front and back surfaces of the glass sheet having the distinctive pattern;
• patterning the shaping mask layer, and shaping the glass sheet having the distinctive pattern on a cell-by-cell basis, wherein the step of shaping the glass sheet having the distinctive pattern on the cell-by-cell basis is performed by a laser process, and the laser process forms a cell-based crack cut after or while shaping the glass sheet having the distinctive pattern on the cell-by-cell basis;
• wet etching on a line of the crack cut on the glass sheet while the shaping mask layer is still on the glass sheet to form a chamfer in the glass sheet through the shaping mask layer;
• removing the shaping mask layer, and tempering the glass sheet having the distinctive pattern while simultaneously tempering a side surface of the glass sheet via the crack cut;
• forming a cell-based functional layer on the back surface of the glass sheet having the distinctive pattern, wherein the step of forming the functional layer includes:
• forming a cell-based print layer on the back surface of the glass sheet having the distinctive pattern except the transmission portion;
• and
• forming a camera window by separating the glass sheet having the distinctive pattern into cells,
• wherein the forming the cell-based distinctive pattern on the front surface of the glass sheet by the etching process is performed such that either a wet etching process or a dry etching process is performed once or multiple times, or the two etching processes are sequentially performed, and
• each etching process forms the same or a different distinctive pattern.
